Synthesis of mesoporous molecular sieves and their application for catalytic conversion of polyaromatic hydrocarbons
- Pennsylvania State Univ., University Park, PA (United States)
Since Mobil workers invented the mesoporous molecular sieves in 1992, their synthesis and application have become interesting research subjects. In this work, we synthesized mesoporous molecular sieves with pores of {approximately}30 {Angstrom} in diameter, and examined their catalytic activity for the conversion of polycyclic aromatic hydrocarbons (in the reactions of hydrogenation of naphthalene and phenanthrene and isopropylation of naphthalene). Three series of mesoporous molecular sieve catalysts with varying Si/Al ratios were prepared using three different aluminum sources and tested for the above reactions. Our results showed that the type of aluminum source used in the preparation plays an important role in their catalytic activity. The catalysts prepared both with aluminum isopropoxide and aluminum sulfate showed good activity both in hydrogenation and alkylation reactions; however, the one with Catapal alumina was not. This could be due to the difference in the nature of active sites in these materials prepared with different aluminum sources.
